Antiapoptotic effects of HSP-70 in vitro. (a–f) Representative western blot images showing the protein levels of HSP-70, Bcl-2, Bax, and cleaved caspase-3. β-Actin was used as an internal control. (g) Representative dot plots of cell apoptosis were showed after Annexin V/PI dual staining. (h) The percentage of apoptotic cells was represented for both early and late apoptotic cells. Every experiment was repeated at least three times. Error bars indicate mean ± SD (^∗P < 0.05; ^∗∗P < 0.01; ^∗∗∗P < 0.001).
